release the transcript of that phone call. he says he's thinking about it. abc's david wright starts us off at the white house. >> reporter: tonight, house speaker nancy pelosi is setting a thursday deadline for the trump administration to hand over a whistleblower complaint against the president for congressional review or else, she says, be prepared for "a whole new stage of investigation." at issue is what exactly was said in a july phone call the president had with the leader of ukraine. >> the conversation i had with the president of ukraine was absolutely perfect. and people better find out who these people are that are trying to subvert our country, because here we go again. >> reporter: "the wall street journal" reports trump repeatedly, eight times, pressured the foreign leader to investigate joe biden's son, hunter. after first refusing to say if biden came up on the call, today trump seemed to acknowledge the leaders did discuss the former

vice president. >> the conversation i had was largely congratulatory, was largely corruption and all of the corruption taking place. was largely the fact that we don't want our people like vice president biden and his son creating to the -- the corruption already in the ukraine, in ukraine. >> reporter: ukraine's foreign minister is now backing up trump's assertion that he didn't pressure anybody. >> there was no pressure. that was not pressure. i know when i give pressure and that was not pressure. >> well, if that is the case, then why doesn't the president simply release the transcript of that call? >> reporter: today president trump didn't rule that out. >> we'll make a determination about how to release it, releasing it, saying what we said. the problem is when you are speaking to foreign leaders you don't want foreign leaders to feel that they shouldn't be speaking openly. >> reporter: but the trump

administration has so far refused to release the whistleblower complaint to congress. even after the inspector general for the director of national intelligence determined the complaint was credible and of urgent concern. this weekend, former vice president biden hit back at trump. >> trump's doing this because he knows i'll beat him like a drum. and he's using the abuse of power and every element of the presidency to try to do something to smear me. >> david wright joins us live from the white house. david, in that letter, speaker pelosi said she expects it to be turned over to congress by thursday? >> reporter: yes, that's when the director of national intelligence, the acting director, is scheduled to appear at an open session. pelosi warns if the administration fails to turn it over by then, she says they will be entering a grave new chapter of lawlessness. tom? >> david, thank you. and now to a shakeup in the

in it. >> rachel, joining us from the campaign trail. the third fund-raising quarter ends at the end of this month. senator booker telling you the future of his campaign depends on his fund-raising? >> reporter: that's right. he put a fund-raising email out, saying if he doesn't get that $1.7 million in just about a week, he's out. his campaign raised about $300,000 since, but that's only a small fraction of what he needs. >> rachel, thank you. we move to the multiple storm threats at this hour. the tropics very active in both the pacific and atlantic. these images from cabo in mexico's baja peninsula. after the hurricane struck from the west. and tonight, a new threat in the atlantic. tropical storm karen. triggering storm watches and emergency preparations in puerto rico. rob, it's busy out there.

lightly in today's world. >> reporter: police say it took 12 hours to apprehend diehl, who tonight is in jail and being held without bail. police have not yet executed a search warrant on his home. but diehl is charged with threatening to use a weapon of mass destruction, which is a third degree felony. tom? >> stephanie, thank you. also tonight, former nfl star antonio brown melting down in a very public way, on social media, after being cut by the patriots amid a sexual assault investigation. instead of taking to the field, he was taking on nfl owners taking shots on other players. tonight, the apparent revenge tweets he later deleted. here's kaylee hartung. >> reporter: tonight, the nfl's biggest lightning rod going into a full meltdown. antonio brown's twitter tirade starting with a declaration, "will not be playing in the nfl anymore, these owners cancel deals and do whatever they want." brown making it clear he'll go after money that was guaranteed by the patriots and raiders. >> he has $40 million on the line. all of these wounds are self-inflicted. >> reporter: the patriots fired the embattled wide receiver on
